For the (anal) artist among us. This tutorial requires only 15 sheets of paper and scissors. Technically, because of the cutting of the paper, this swan is kirigami, not origami. That said, assembling 471 paper triangles into this beautiful swan is the work of angels.
It's Monday, and once again it's time to highlight some of the community submissions posted to the Math Craft corkboard. In addition, I thought we'd take a look at having fun with the geometrical properties of polygons and circles by using one of the best circles I know, the penny.
If you're a fan of Sicilian foods, you might also like these chickpea fritters. They're crispy golden triangles of fried chickpea dough. Yum! These crispy chickpea fritters, known as panel, are crunchy and salty Sicilian street treats. And it only takes a few ingredients! This is great for a savory appetizer or a quick dazzle-your-friends snack.
It's Monday, time to highlight some of the community submissions posted to the Math Craft corkboard. One of these posts inspired me so much, I think it merits a closer look. Today, I present a "simple" method for making a golden spiral using just a straight edge, a compass, and a template, inspired by RJ Ellicock's golden ratio post.
So, this is a type of origami that is called golden venture origami. This type of origami is made of hundreds to thousands of little intersecting triangles. This took about 2-3 three hours, the picture is pretty bad because it was taken at school with a cell camera. But I hope this inspires you to make some of your own! This type of origami is in essence very easy to make but takes a lot of time and effort to make. However if you get really good at it, you can do it without even looking at ab...
I decided I would make those earrings I alluded to in Monday's Post on orderly tangles. I had to shrink the templates down so that the triangles are about 2 cm on a side. I used 110 lb cardstock and and painted them using metallic leafing paint in gold, silver, copper, and brass. I would put up a tutorial, except I think that this project would be too frustrating for most people. All I can suggest is that you make the orderly tangle of 4 triangles multiple times and just keep shrinking the si...
Their were many pedestrians in the scene as,they seen firefighters struggling with the horrifying disaster and they couldn't do much only continue to stare as bodies continued to drop..
This pool shooting video demonstrates the proper stance for a power break, or shooting the cue ball at the triangle form at the beginning of a game. Your feet should be wide apart, body weight forward, make several practice shots, and a strong shot with straight follow through. By using proper technique, you will open any billiard game with a statement. Stand for a power break when shooting pool.
To get maximum control over your pitch shots you need to learn to swing the body, not the arms. David Blair demonstrates how the weight of the golf clubhead can do the work for you. Set the triangle between the arms and the body and maintain this throughout the swing. Pitching will become easy. Make pitching easier.
Last post, we looked at fractal cookies based off of the recipe by Evil Mad Scientist Laboratories. In this post, we'll follow their recipe for fractal cupcakes based off of the Koch Snowflake, which we used previously to decorate pumpkins for Halloween.
Halloween is coming up, so many of you may have a need or desire to carve a pumpkin and turn it into a Jack O' Lantern. This week we are going to explore carving our pumpkins into interesting geometric shapes. In this post, we will carve the pumpkins into spherical versions of polyhedra, and in Thursday's post we will carve 2 dimensional stars and some simple fractal designs into the pumpkins.
The "slide-together" paper construction method is a fun and satisfying way to build 3D geometric objects. It only requires paper, scissors or an exacto knife, and some patience.
You can do some pretty cool stuff with the golden ratio. The image above is made from taking each quarter-circle in the golden spiral and expanding it into a full circle. In the second image, the spiral and the golden rectangles are overlaid on the the first image, showing how it works.
This is the procedure for making two origami bears using a square sheet of paper. For this we need a square sheet of paper with one colored side and the other can be white. The steps are:
Each curved module replaces the equilateral triangle of a simple octahedron. Inspired and copied from Cory's post with original artwork by Richard Sweeney
This article shows and talks about the devastating event that happen during the 1911's, it also shows how this fire changed many perspectives towards a fire.
The tragedy of the Triangle Shirtwaist Fire repeated itself. Over 25 Bangladeshi workers died in a sweatshop who sewed clothes for JC Penney, Target, Abercrombie and Fitch, and many more. Check out the link.
Download Full Episodes of Vampire Diaries Vampire diaries is about Elena Gilbert and Stefan Salvatore. Elena falls in love with Stefan who is a vampire and soon get caught with a love triangle with Stefan's older brother named Damon who is also a vampire. Stefan and Damon are still hunted by their past with Katherine Pierce.
Paper Donut is a collaborative graffiti project between Justine Ricaud and Alexis Facca. The French duo paint geometrical illusions as urban art (with the exception of the gallery installation below). They've also posted some detail shots that give you some sense of how it was done.
This video explains how to construct a model of a geodesic dome from paper and shows how to draw triangles with a compass and straight edge. Construct a model of a geodesic dome.
Can you dissect an equilateral triangle into pieces that can be rearranged into a square? If you think you can, you may have mastered the Pythagorean theorem.
In this tutorial, we learn how to make a fondant sushi themed cake. You will need: brown, yellow, and red for your fortune cookie colors. To get the colors right, mix them together and then combine with fondant. Then, roll out the fortune cookie and lay it over a bowl to make it look like the fortune cookie shape. Let this dry overnight. From here, create a small bowl with greens to make the bowl that the soy sauce would go in. Create two chop sticks with brown fondant, rolled out first and t...
Possibly using Johnny Knoxville, Bam Margera and Spike Jonze, dressed up as their finest elderly counterparts. The 3 should go to a local Free Health Clinic to be tested for STD's. They should argue in the office and make it clear there is a love triangle in the nursing home where they live. Also that Jonze's character is a real slut. One could bring a teenager with them posing as a grandchild, to "teach them a valuable lesson about whores" at an early age. As loud and graphic as possible. Th...
Choosing the right tripod stand can be a difficult decision, but if you want to avoid the hassle and save some money, making your own easy to use tripod can be the best way to go. If this tennis ball tripod isn't right for you, then maybe this disposable razors one by Instructables user Jawasan will do. This tripod stand only works for small cameras, so make sure yours is light enough before you start.
In this tutorial, we learn how to wear a scarf for fall and winter. First, take a scarf in any material and color that you would like for your outfit. Use a solid, lace, print, or anything else that you would like to use. After you have picked it out, you can tie it around your neck so one side is tied on the back and one is on the front. Or, you can leave both sides in the back and make it loose around the neck or tight. You can also spread the scarf out so it's a slight triangle in the fron...
This 3ds Max software tutorial covers how to turn your mesh into Hexagon poly’s which creates a smoother mesh. This is a technique Dave learned from Toru Hasegawa that he is sharing with all of us. You essentially triangulate a quad poly surface then collapse the triangles to have hexagons. Watch and learn how to convert a mesh into hexagon shaped polys with Classic Mesh Smooth in this 3ds Max modeling tutorial. Convert a mesh to hexagon polys in 3ds Max.
Fractals and stars are two of the most beautiful and complicated-looking classes of geometric objects out there. We're going to explore these objects and how to carve them on a pumpkin. Unlike the last one on carving polyhedral pumpkins, where we used the entire pumpkin to carve a 3 dimensional shape, the pumkin carving in this post will involve two-dimensional images on a small part of the pumpkin's surface.
Have you seen the impossible triangle and wondered how it was created? This video will show you how to draw an impossible triangle using Microsoft Paint. Draw an impossible triangle in MS Paint.
After Cory Poole posted some great Escher snowflakes, and Cerek Tunca had the great idea of using it as a base for a tetrahedron, well, I just had to give it a go. I will post a few more pictures and variants later (I think this was what Cerek was envisaging—if not let me know!)
These are a few examples of my latest craze. It is basically a 3d weave of cocktail sticks—just lots of them. I have made them from chopsticks and skewers as well, but have given those as presents and don't have any pictures.
+Tyler Neylon, a programmer and mathematician currently specializing in iOS app development, recently posted a fun project to his Google+ profile: 50 designs with 50 LEGO pieces, a set of 51 photos. Given a small 50-piece Lego set this past Christmas (well, Tyler admits: "...58 [pieces], actually, but many of them are very small, as you can see"), he craftily stretched his imagination to create 50 different models, though the kit included instructions for only 3.
This Ship is an origami classic, easy to do and it floats well. You can do the ship just by this Video or also use the steps below.
Are you bored of draping a scarf around your neck in a single loop like everybody else? Tie both ends of a long scarf to form a large loop, then loop the scarf around your neck twice to create a DIY infinity scarf.
This three dimensional Sierpinski tetrahedral structure was created with a lot of help from my Year 10, 12 and 13 classes. It is inspired by the Sierpinski triangle fractal.

If you haven't seen one, a comet is one of the most spectacular astronomical objects in the sky, partially because it is so close to Earth. At the closest, it is only 1.3 a.u. (194,477,400 kilometers) away from Earth. Comet C/2009 P1 Garradd was discovered by Gordon J. Garradd on August 13, 2009. It never comes closer to the sun than Mars's orbit. Usually, a comet moves fast, but it has stopped moving so fast recently, making it really easy to observe. It can be observed by a telescope or wit...
Math Craft admin Cory Poole provided quite a few recipes for sonobe models in his blog, and I followed one to make the pentakis dodecahedron here.
This is The Substream's "The Film Lab" series on lighting basics. This episode covers Rembrandt Lighting.
Last Thursday's post demonstrated how to Make Yin-Yang Pillow boxes, which were based on equilateral triangles and squares. The units for making these boxes were created by Phillip Chapman-Bell, who runs an amazing origami blog and has a spectacular flickr photostream. Using these units, you can make also make 4 of the 5 platonic solids. I made an additional template based on the regular pentagon so that the dodecahedron can be built completing the set.
In Monday's post, we created a sliceform model of a hyperbolic paraboloid. In today's post, we will create a similar model using skewers. The hyperbolic paraboloid is a ruled surface, which means that you can create it using only straight lines even though it is curved. In fact, the hyperbolic paraboloid is doubly ruled and is one of only three curved surfaces than can be created using two distinct lines passing through each point. The others are the hyperboloid and the flat plane.
